Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1546518-2 is determined by the following critical parameters:

Primary Substitution Criteria:

Number of Positions: 2
Header Orientation: 90°, Right Angle
Termination Style: Solder
Mounting Type: Through Hole
Material Flammability Rating: UL94 V-0
Contact Mating Finish: Tin

Secondary Compatibility Factors:

Pitch tolerance: 0.200" (5.08mm) or 0.197" (5.00mm) are functionally equivalent within standard connector spacing tolerances
Shrouding configuration: 2-side shrouded is the primary match; 4-side shrouded variants provide enhanced EMI shielding but maintain mechanical and electrical compatibility
Housing material: Polyamide (PA66/PA46) and Polybutylene Terephthalate (PBT) are both acceptable thermoplastic materials meeting UL94 V-0 requirements
Contact material: Brass and Phosphor Bronze are both acceptable conductor materials with tin plating

Substitute parts are grouped into two categories: direct pitch equivalents (5.08mm) and near-pitch equivalents (5.00mm). All listed substitutes maintain the core functional requirements of 2-position, 90° right-angle, solder-terminated, through-hole terminal block headers with appropriate shrouding and flammability ratings.

Engineering Selection Recommendations

Direct Pitch Equivalents (0.200" / 5.08mm):

For applications requiring exact pitch matching with the original 1546518-2, the following active components are recommended:

Molex 0395320002: Active product status with ROHS3 compliance. Identical pitch and shrouding configuration. Suitable for new designs and legacy system replacements.
Adam Tech EBQA-02-D: Active product status with ROHS3 compliance. Identical pitch and 2-side shrouding. Available in green housing variant.
Amphenol PCD ELFH02220: Active product status with RoHS compliance. Identical pitch and 2-side shrouding. Packaged in tray format.
Amphenol PCD ELFH02210: Active product status with ROHS3 compliance. Identical pitch with 4-side shrouding for enhanced EMI performance. Bulk packaging available.
Amphenol PCD ELFH02230: Active product status with RoHS compliance. Identical pitch with 4-side shrouding. Tray packaging.

Near-Pitch Equivalents (0.197" / 5.00mm):

For applications where minor pitch tolerance is acceptable, the following components provide functional equivalence:

Weidmüller 1571130000: Active product status with RoHS compliance. Pitch of 0.197" (5.00mm) with 2-side shrouding. Offers higher current rating (18A IEC) and voltage rating (400V IEC). Orange housing variant.

All substitute components maintain UL94 V-0 flammability rating, tin contact mating finish, and through-hole solder termination. All active substitutes provide documented electrical ratings (15A UL, 300V UL minimum) and operating temperature ranges of -40°C to 105°C, exceeding the specifications of the obsolete original component.

Frequently Asked Questions (FAQ)

Q: Can I use a 5.00mm pitch component as a substitute for the 5.08mm pitch original?

A: Yes. The 0.197" (5.00mm) pitch components are functionally equivalent substitutes. The 0.08mm difference falls within standard connector spacing tolerances and does not affect mechanical or electrical compatibility in typical applications. However, verify PCB layout compatibility before implementation.

Q: What is the difference between 2-side and 4-side shrouded variants?

A: Both configurations maintain the same electrical and mechanical functionality. The 4-side shrouded variants (ELFH02110, ELFH02130, ELFH02210, ELFH02230) provide additional EMI shielding and mechanical protection. The 2-side shrouded variants (ELFH02120, ELFH02140, ELFH02220, EBQA-02-D, 0395320002) are direct functional equivalents to the original 1546518-2. Selection depends on application-specific EMI requirements.

Q: Are all substitute parts RoHS compliant?

A: All listed substitute components are RoHS compliant (either RoHS or ROHS3 certified). The original 1546518-2 is marked as "Not applicable" for RoHS status due to its obsolete classification. All active substitutes meet current environmental compliance standards.

Q: What is the difference between Molex, Weidmüller, Adam Tech, and Amphenol PCD variants?

A: All manufacturers produce functionally equivalent 2-position, 90° right-angle terminal block headers with identical electrical ratings (15A UL, 300V UL) and flammability ratings (UL94 V-0). Differences include housing material composition (PA66, PA46, or PBT), contact material (Brass or Phosphor Bronze), and packaging format (Bulk or Tray). Selection is based on availability, packaging requirements, and design preference.

Q: Can I substitute the Weidmüller 1571130000 for the original part?

A: Yes. The Weidmüller 1571130000 is functionally equivalent with a 0.197" (5.00mm) pitch. It offers enhanced electrical ratings (18A IEC, 400V IEC) and a wider operating temperature range (-50°C to 100°C). The component is active and RoHS compliant. Verify PCB layout compatibility due to the minor pitch difference.

Q: What packaging options are available?

A: Substitute components are available in three packaging formats: Bulk (loose components), Tray (organized tray packaging), and unspecified packaging. Molex 0395320002 and Amphenol PCD ELFH02210 are available in Bulk. Amphenol PCD ELFH02120, ELFH02130, ELFH02140, ELFH02220, and ELFH02230 are available in Tray. Select packaging based on assembly process requirements and inventory management.

Q: Are all substitutes available in black housing?

A: Most substitutes are available in black housing. The Adam Tech EBQA-02-D is available in green housing. The Weidmüller 1571130000 is available in orange housing. Housing color does not affect electrical or mechanical function; selection is based on design preference or application-specific requirements.

Q: What is the current inventory status of substitute parts?

A: All listed substitute components are in stock. Molex 0395320002 has the highest inventory (7271 pcs), followed by Amphenol PCD ELFH02210 (4638 pcs). Amphenol PCD ELFH02120 has the lowest inventory among active substitutes (672 pcs). Verify current availability with supplier before design finalization.
